Available in PDF, EPUB and Kindle. Book excerpt: The goal of this Trident project was to develop an independent control scheme to allow a team of autonomous tugboats to move a large disabled vessel, such as a barge, to a desired position and orientation. Independence refers to the extent to which each tugboat's actions were free from knowledge of the locations and actions of other tugboats. Performance of the team was quantified by measuring the positional error and time required to affect the motion, while respecting maximum power constraints on the thrust. Applications of the project include difficult or dangerous tasks such as moving disabled vessels or vessels "not under command" through hostile or dangerous areas, and transportation of large objects such as marine construction equipment, off-shore bases, drilling platforms, and sonar arrays. Although it would be ideal to increase both the independence and performance of the system, it must be realized that by increasing one of these, the other is typically degraded. In order to measure performance, a control strategy (the baseline) was designed that required the attachment points of all tugboats to be known. However, this architecture was not desirable, since it was less independent of system knowledge. In contrast, to allow for the elimination of known tugboat location, an adaptive control strategy was developed which resulted in degradation of performance. These two Scenarios were explored and in the course of solving them, the tradeoff between performance and independence was quantified. To the author's knowledge, this is the first study of its kind and complexity. Although previous work has studied adaptive control of a multi-input and multi-output system, its extent and focus was not close to this research. Each tugboat used on-line adaptive control methods to compensate for the unknown actions of other swarm members. The analysis was verified through simulation. In addition, an experimental proof-of-concept device was built and in-water experiments were used to validate the results. An incremental approach to experiment design was used to mitigate the challenges of in-water experimentation.

Book Synopsis Cooperative Manipulation on the Water Using a Swarm of Autonomous Tugboats by :
Download or read book Cooperative Manipulation on the Water Using a Swarm of Autonomous Tugboats written by and published by . This book was released on 2008 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we present a strategy that allows a swarm of autonomous tugboats to cooperatively move a large object on the water. The two main challenges are: (1) the actuators are unidirectional and experience saturation; (2) the hydrodynamics of the system are difficult to characterize. The primary theoretical contribution of the paper addresses the first challenge. We present a tracking controller and force allocation strategy that, despite actuator limitations, result in asymptotically convergent tracking for a certain class of reference trajectories. The primary practical contribution is the introduction of a set of adaptive control laws that address the second challenge by compensating for unknown, and difficult to measure, hydrodynamic parameters. Experimental verification of the controllers is presented using a 1:36 scale model of a U.S. Navy ship, inside the Naval Academy's unique 380 ft testing tank.

Book excerpt: Orson Scott Card and Aaron Johnston return to their Ender's Game prequel series with this first volume of an all-new trilogy about the Second Formic War in The Swarm. The first invasion of Earth was beaten back by a coalition of corporate and international military forces, and the Chinese army. China has been devastated by the Formic's initial efforts to eradicate Earth life forms and prepare the ground for their own settlement. The Scouring of China struck fear into the other nations of the planet; that fear blossomed into drastic action when scientists determined that the single ship that wreaked such damage was merely a scout ship. There is a mothership out beyond the Solar System's Kuiper Belt, and it's heading into the system, unstoppable by any weapons that Earth can muster. Earth has been reorganized for defense. There is now a Hegemon, a planetary official responsible for keeping all the formerly warring nations in line. There's a Polemarch, responsible for organizing all the military forces of the planet into the new International Fleet. But there is an enemy within, an enemy as old as human warfare: ambition and politics. Greed and self-interest. Will Bingwen, Mazer Rackam, Victor Delgado and Lem Juke be able to divert those very human enemies in time to create a weapon that can effectively defend humanity in the inexorable Second Formic War?

Book excerpt: Terrorism: Commentary on Security Documents is a series that provides primary source documents and expert commentary on various topics relating to the worldwide effort to combat terrorism, as well as efforts by the United States and other nations to protect their national security interests. Volume 144, Autonomous and Semiautonomous Weapons Systems, examines the impact of robots and autonomous and semiautonomous weapons systems on the waging of modern warfare. It considers the likely effects of emerging technological innovations in this area from both a political and strategic standpoint, in addition to considering the implications of such technologies within the context of the law of armed conflict and international humanitarian law. This volume is divided into three sections: (1) U.S. policy and approaches to the use of autonomous and semiautonomous weapons systems; (2) U.S. armed forces use of such weapons systems; and (3) potential terrorist use of such weapons systems. Official policy documents from the DoD and the U.S. Army and Air Force are complemented by reports from the Strategic Studies Institute/Army War College Press and other U.S. military sources.
Book Synopsis Swarming and the Future of Conflict by :
Download or read book Swarming and the Future of Conflict written by and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swarming is seemingly amorphous, but it is a deliberately structured, coordinated, strategic way to strike from all directions, by means of a sustainable pulsing of force and/or fire, close-in as well as from stand-off positions. It will work best-perhaps it will only work-if it is designed mainly around the deployment of myriad, small, dispersed, networked maneuver units (what we call "pods" organized in "clusters"). Developing a swarming force implies, among other things, radical changes in current military organizational structures. From command and control of line units to logistics, profound shifts will have to occur to nurture this new "way of war." Our study examines the benefits- and also the costs and risks-of engaging in such serious doctrinal change. Examples of swarming can be found throughout history, but it is only now able to emerge as a doctrine in its own right. That is largely because swarming depends on a devolution of power to small units and a capacity to interconnect those units that has only recently become feasible, due to the information revolution.
